Intruduce a new state 'active' in io_poll_iocb to indicate whether io_poll_wake() should queue a task_work. This new state will be set to true initially, be set to false when starting to queue a task work, and be set to true again when a poll cqe has been committed. One concern is that this method may lost waken-up event, but seems it's ok. io_poll_wake io_poll_task_func t1 | t2 | WRITE_ONCE(req->poll.active, true); t3 | t4 | io_commit_cqring(ctx); t5 | t6 | If waken-up events happens before or at t4, it's ok, user app will always see a cqe. If waken-up events happens after t4 and IIUC, io_poll_wake() will see the new req->poll.active value by using READ_ONCE(). Echo_server codes can be cloned from: https://codeup.openanolis.cn/codeup/storage/io_uring-echo-server.git, branch is xiaoguangwang/io_uring_multishot. Without this patch, the tps in our test environment is 284116, with this patch, the tps is 287832, about 1.3% reqs improvement, which is indeed in accord with the saved add_wait_queue() cost.
